Exhaust Port Spacing Rb26 Vs Rb25

[dnb]

hey guys,sorry for the random post but im about to make a manifold for an rb26 and i only have an rb25 head to work from.

i know the stud patterns are different,thats not a problem.

i assume the ports are spaced the same on both engines,am i correct?

cheers

You are correct, the ports are spaced the same. When I TT'd the RB25 I just cut and rewelded a couple of the flanges, then match ported.
